CI, confidence interval.

*Enrichments were calculated as ratios: percentage of regions containing the indicated motif(s) vs. percentage of control regions with the same motif(s). Enrichment ratios were computed 1,000 times, each time with a different set of control regions. Control regions were randomly selected such that the distance between the control region and the closest transcription start site (TSS) has the same probability distribution as the distance between the TileMap ranked region and the TSS.
